document.caretPositionFromPoint()

[BenjaminAster]

Description

The document.caretPositionFromPoint() method is currently not implemented in WebKit. Instead, WebKit implements the non-standard document.caretRangeFromPoint() method, which returns a Range instead of a CaretPosition. Note that Chromium also only recently added support for the standardized method.

+1 to this proposal

I think this proposal should explicitly include supporting getting caret positions inside shadow DOM using the options parameter (https://drafts.csswg.org/cssom-view-1/#dictdef-caretpositionfrompointoptions). That has been a popular ask from web developers, but Chromium is currently the only engine that implements that part of the spec.

There appear to be basically no tests in WPT for this?
